Josh Wood Blending Brush, Grey Root Touch Up, Dark Blonde, Vegan, 20ml | Covers grey regrowth instantly, salon-created formula, quick at-home root touch up between permanent colouring

I have tried so many root cover products from sprays to powders and none of them did a good job. I have blonde coloured hair and getting more and more greys, I really don’t like grey roots showing so I dye the roots as often as every two weeks which is not good for my hair. For ages I’ve been looking for a root cover to be able to extend the time between colouring. When I saw this product I liked the concept of putting it on with a brush on damp hair so I thought I’d give it a go. And wow! It’s amazing! It covers up all the greys and looks very natural. The best root cover up I have found so far.

I have light blond hair and this matched in perfectly, don't be put off by the colour it comes out of the container. It covered my grey regrowth without trace of a line. Do test it for colour match and apply it the day before if you need perfect hair roots for a special event as it weighs the hair down when first applied, one wash on the day will not affect the colour.My root touch up had lasted four days before a salon treatment and would have been effective for longer.I used this when it first came out some years ago. It was good then but this is even better. Brilliant, so pleased I found it again.

The colour had no impact at all .

Great colour and coverage for grey hair. So easy to use and stores well. Easy for travel too.

Like this product, have used before and bought again as doesn’t leave a crispy feel, apply to wet hair, which I prefer to the spray on ones, however, have noticed this time it leaves behind a red’ish tint, so might look for a different make next time

A brilliant product to extend colour between hair appointments.

Rather than roots I use this colour on more or less grey hair from the brush on a glove blended with leave-in conditioner, rubbed or streaked into sides, crown and strands then brushing neat into certain areas (I do have shortish hair). I stopped colouring three years ago and don't wish to be completely grey or white. It gives a nice tawny look to the hair but does need doing every couple of weeks, brushed well in after washing and almost drying hair.

I like the formula of this - it's a more effective cover than powders, and quite easy to use. However it really only lasts the one time you use it - then it washes out. I used it three times in a row, and after the third time, my roots had a yellowish tint, but then I went to the salon and had my roots coloured properly. It's vastly more expensive to use in this way, than the powders or sprays, so I may buy it again, but only for certain conditions.
